为了对矿区以景观资源、地质遗迹资源、文物古迹资源、土地资源、水资源等为代表的矿山资源环境在资源开发过程中遭到不同程度的损害及浪费等情况进行安全评价,对矿区资源环境所受到的威胁进行分析,并以此为基础构建了矿山资源环境安全评价指标体系。整个指标体系同时考虑了资源环境风险的可能性及后果损失度,以更加全面地反映资源环境的安全程度(或风险水平)。同时分析了指标重要性评判、排序过程中存在的未确知性,以及传统层次模型中判断矩阵一致性检验方法的局限性,将未确知有理数引入属性层次模型中,建立了基于未确知层次分析模型的矿山资源环境安全状况评价模型。在评价过程中,首先引入未知有理数建造未确知判断矩阵;其次,利用未确知判断矩阵计算评价准则的综合重要程度值,以判断矩阵中某个评价准则相对其他所有准则的综合重要程度;然后,计算各级评价准则的归一化权重,以确定对矿山整个资源环境安全有影响的影响因素次序;最后,对矿山资源环境安全状况进行模糊综合评价,从而确定矿山资源环境的安全等级。通过实例分析验证了矿山资源环境安全评价模型的正确性。
In order to carry out the safety assessment of mine resources and environment, such as landscape resources, geological heritage resources, cultural relics and historic sites, land resources and water resources, which were damaged and wasted in different degrees in the process of resource development, The threats it suffered were analyzed, and on the basis of which the index system of mine resources and environment safety evaluation was constructed. The whole indicator system considers both the possibility of resource and environmental risks and the degree of loss of consequence so as to more completely reflect the degree of safety (or risk level) of resources and environment. At the same time, the paper analyzes the importance of indicators, the unascertained existence in the process of sorting, and the limitations of the consistency test of judgment matrix in the traditional hierarchical model. The unidentified rational numbers are introduced into the attribute level model, Analyze the mine resource and environment safety evaluation model. In the process of evaluation, the unidentified judgment matrix is constructed by introducing the unknown rational number first. Secondly, the unidentified judgment matrix is used to calculate the comprehensive importance value of the evaluation criteria to judge the comprehensive importance degree of some evaluation criterion relative to all other criteria in the matrix. Then, the normalized weight of evaluation criteria at all levels is calculated to determine the order of influencing factors on the safety of resources and environment of mine. Finally, fuzzy comprehensive evaluation of the safety of resources and environment of mines is carried out to determine the safety level of mine resources and environment. Through the example analysis, the correctness of mine resources and environment safety evaluation model is verified.
